Conventional Bottom and Top Cementing Plug (Wiper Plug)
Cementing plug also called wiper plug is a rubber plug used to separate the drilling mud from other fluids. There are two types of cementing plugs, bottom plug and top plug. Non-rotating type and common type are two options for customers. We provide non-rotating type plugs that have locking teeth on both the top and bottom plugs and float collars, allowing the plugs to lock together during drill-out.
Conventional Bottom and Top Cementing Plug (Wiper Plug) is manufactured with graded rubber that is fused onto a composite or aluminum core. Top cementing plug can be used when a dual plug system is not required and bottom cementing plug can be used when a dual plug system is required.
